HDR stands for High Dynamic Range. With HDR on your Xbox One S, your TV can display deeper colors and richer contrast, meaning the picture will appear more vibrant and realistic than on a regular HDTV.

To display HDR, you must have HDR content. Content that's recorded for regular TV and non-HDR games won't appear different—to see true HDR, look for HDR UltraHD Blu-ray discs, HDR content in video streaming apps, and HDR games.

There are two HDR formats that your TV manufacturer can choose to support: HDR10 and Dolby Vision. Your TV must support HDR10 to display HDR content from your Xbox One S. See Troubleshooting 4K and HDR on Xbox One S for more info.

Turning on HDR

If your 4K TV is set up correctly, it should automatically play HDR content—you don't have to change anything on your Xbox.

To check, double-tap the Xbox button to open the guide, go to Settings > All settings, choose Display & sound > Video output, and then choose Advanced video settings. Both the Allow 4K and the Allow HDR settings should be checked if you want HDR on.

Also, check your TV's settings menus to make sure HDR is turned on. Your TV must also support the HDR10 media profile to display HDR.
